Modern Quarrying April-May 2016

ON THE COVER

Industry first: One hundred percent of all rock drill services can be completed without removing the drill from the feed.

Technical Specifications: Cat MD5075C Hole diameter range 76,2-114,3 mm Hole depth maximum 31,2 m Engine

Steering is provided by the drill’s two joystick CANbus controls and foot pedals for precise positioning. A high resolution in-cab display enables touch screen naviga- tion for Cat Connect technologies like Drill Assist, which monitors main hydraulic systems and automatically adjusts to pre-pro- grammed parameters. Drill Assist incorporates anti-jam, anti-plunge and anti-plug, resulting in higher productivity and increased life of the drill string. Other touch screen readouts include a drill depth indicator, which ensures all holes in a pattern are drilled to the planned depth. This helps promote a better floor, and reduces the need for secondary blasting. Optimum drilling Like the MD5075C, the latest generation Cat MD5150C (which replaces the Cat MD5125) comes with high productivity fea- tures refined via extensive in-field production studies. The latest MD5150C model upgrade was announced to the market just over a year ago. Intended for higher production requirements, hole diameters on the Cat MD5150C range from 101,6 mm to 152,4 mm with a multi-pass hole depth to 31 m. Power is provided by a Cat C11 engine rated at 287 kW. “Choosing between the two drills will clearly depend on the site conditions and downstream targets,” adds Glaus. “Either way, both models lead in their class to ensure that high drill uptime keeps production flowing.” www.cat.com/mqmdrill
